“…The sizes of these structures are correlated closely and posi¬ tively with their functional activity (Martin et al, 1973;Lavia et al, 1985;Murray, 1992 (Kirkland et al, 1981;Janssens et al, 1983;Stewart et al, 1983;Cheng et al, 1985 (Murphy and Friesen, 1988). Growth hormone recep¬ tors are also found in the uterine tissues (Rose et al, 1993;Byatt and Collier, 1995 (Gunin, 1996).…”

The aim of this study was to examine the effect of growth hormone on the uterine response to oestradiol. Ovariectomized rats were treated with a single injection of oestradiol dipropionate (10 (Biro and Eneroth, 1987;Malven et al, 1995;Mustafa et al, 1995 (Sartor et al, 1983;Chilton and Daniel, 1987;Bezecny et al, 1992), although uterine weight and endometrial surface area are unaffected (Chilton and Daniel, 1987;Bezecny et al, 1992). However, in hypo¬ physectomized rats, uterine weight increases under the influence of growth hormone, and oestradiol enhances this effect (Grattarola and Li, 1959 Gunin (1996).

“…The relationship between the variation of ovarian hormones during the oestrous cycle and the morphological pattern of the endometrium has been extensively studied in various species in vivo by light microscopy (Davies & Hoffman, 1973) and electron microscopy (Anderson, Kang & Desombre, 1975;Wynn, 1977;Herbst & Multier-Lajous, 1980;Cornillie, Lauweryns & Brosens, 1985;Lavia, Roberts, Walker & Anderson, 1985). Cell culture has provided a powerful tool for studying many aspects of cell growth and function under controlled conditions.…”

The effects of oestradiol-17 beta, progesterone and oestrone-3-sulphate were studied in primary cultures of guinea-pig endometrial glandular epithelial cells. Comparative ultrastructural studies were performed by means of transmission electron microscopy on cells grown either without hormones or with oestradiol-17 beta (2 nmol/l), oestradiol-17 beta (2 nmol/l) plus progesterone (50 nmol/l), or oestrone sulphate (0.1 mumol/l). In the control medium, without steroid hormones, the majority of epithelial cells were poorly differentiated, although numerous small mitochondria were present and abundant lipid droplets could be observed. Oestradiol-17 beta stimulated metabolic activity in the cells. Progesterone added to oestradiol-17 beta-primed cells stimulated the development of the endoplasmic reticulum-Golgi system. Oestrone sulphate induced a higher level of differentiation characterized by large clear mitochondria, well-developed Golgi complexes, and active nuclei, suggesting secretory activity. In all cases, the cultured cells displayed deep invaginations of the nuclear membrane associated with nuclear pores, known as nucleolar channels. After treatment with oestrone sulphate these channels were associated with a characteristic reticular nucleolus. We conclude that cultured endometrial epithelial cells display secretory activity in response to treatment with oestradiol-17 beta plus progesterone, or with oestrone sulphate.
